USS Cassin (DD-372) was a Mahan-class destroyer in the United States Navy before and during World War II. She was the second ship named for Stephen Cassin, an officer in the United States Navy.

Cassin was launched at the Philadelphia Navy Yard on 28 October 1935. She was sponsored by Stephen Cassin's great granddaughter, Mrs. Helen Cassin Carusi Lombard, and commissioned 21 August 1936, with Lieutenant Commander A. G. Noble in command. Mrs. Lombard, at age nine, had also sponsored the first USS Cassin in 1913.

Cassin underwent alterations until March 1937, then cruised to the Caribbean and Brazil. In April 1938 she joined the fleet at Pearl Harbor for the annual fleet exercises in the Hawaiian Islands and the Panama Canal Zone. During 1939, she operated on the West Coast with torpedo and gunnery schools, and on 1 April 1940 was assigned to the Hawaiian Detachment. Cassin sailed on maneuvers and patrol in the Pacific, cruising from February to April 1941 to Samoa, Australia, and Fiji. Fall of 1941 found her calling at West Coast ports.

Cassin was in drydock with Downes and Pennsylvania at Pearl Harbor during the Japanese attack on 7 December 1941. During the attack, an incendiary bomb exploded Downes' fuel tanks, causing uncontrollable fires on board both Downes and Cassin. Cassin slipped from her keel blocks and rested against Downes. Both ships were considered lost, and Cassin was decommissioned as of 7 December 1941. Both ship's hulls were damaged beyond repair but machinery and equipment were salvaged and sent to Mare Island Navy Yard where entirely new ships were built around the salvaged material and given the wrecked ship's names and hull numbers.
